Chemical studies on zooarchaeological remains have been most extensively developed in recent decades, especially those focused on the identification of chemical fingerprints or types of isotopes and their relationships. This paper aims at showing two procedures used for chemical characterization of bones on the basis of spectrometric data obtained by LIBS technique (Laser Induced Breakdown Spectroscopy). One called Standard Addition, a destructive procedure, with a high error degree; the other called Bone Matrix Replacement, a noninvasive method with a relatively low error degree. We expect to gather a methodological and analytical corpus to characterize, efficiently and inexpensively, the chemical fingerprints of diverse archaeofaunal material. Hence, we intend to achieve chemical characterization of archaeological bones in order to address issues related to animal eating habits and mobility in the past.Downloads
